Preferred individual compounds of the formula I which may be mentioned are: 6-[3-(2-methoxycarbonylphenylsulfonyl)ureido]-5-chloro-1-methylpyrazin-2-one and 6-[3-(2-methoxycarbonylphenylsulfonyl)-ureido]-3-methoxy-4-methyl-1,2,4-triazin-5-one.

The compounds of the formula I are in general prepared by the following methods.

According to a first process, the compounds of the formula I are obtained by reacting an aminopyrazinone or aminotriazinone of the formula II ##STR12## in which R¹, R², R³ and E are as defined under formula I, with a sulfonyl isocyanate of the formula III

    X═C═N--SO.sub.2 --A                                (III)

in which A and X are as defined under formula I.

According to a second process, the compounds of the formula I are obtained by reacting an aminopyrazinone or aminotriazinone of the formula II with a sulfonyl carbamate of the formula IV ##STR13## in which A and X are as defined under formula I and R is phenyl, alkyl or substituted phenyl, in the presence of a base.

Finally, the compounds of the formula I can also be obtained by reacting a carbamate of the formula V ##STR14## in which R¹, R², R³, E and X are as defined under formula I and R is phenyl, alkyl or substituted phenyl, with a sulfonamide of the formula VI

    H.sub.2 N--SO.sub.2 --A

    (VI)

in which A is as defined under formula I, in the presence of a base.

If desired, the resulting ureas of the formula I can be converted into addition salts by means of amines, alkali metal or alkaline earth metal hydroxides or quaternary amonium bases. This is effected, for example, by reaction with the equimolar amount of a base and evaporation of the solvent.

The reactions to give compounds of the formula I are advantageously carried out in aprotic inert organic solvents. Such solvents are hydrocarbons, such as benzene, toluene, xylene or cyclohexane, carbon tetrachloride, chlorobenzene, ethers, such as diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, tetrahydrofuran or dioxane, nitriles, such as acetonitrile or propionitrile, or amides, such as dimethylformamide, diethylformamide or N-methylpyrrolidinone. The reaction temperatures are preferably between -20° and -120° C. The reactions of the coupling processes in general proceed as slightly exothermic reactions and can be carried out at room temperature. For the purpose of shortening the reaction time or of initiating the reaction, it is expedient to heat the reaction mixture up to its boiling point for a short time. The reaction times can also be shortened by addtion of a few drops of a base as a reaction catalyst. Particularly suitable bases are tertiary amines, such as trimethylamine, triethylamine, quinuclidine, 1,4-diazabicyclo[2.2.2]-octane, 1,5-diazabicyclo[4.3.0]non-5-ene or 1,8-diazabicyclo[5.4.0]undec-7-ene. However, inorganic bases, such as hydrides, such as sodium or calcium hydride, hydroxides, such as sodium and potassium hydroxide, carbonates, such as sodium and potassium carbonate, or bicarbonates, such as potassium and sodium bicarbonate, can also be used as the bases.

The end products of the formula I can be isolated by concentrating the mixture and/or evaporating off the solvent and can be purified by recrystallization or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons.

The intermediate products of the formulae III, IV and Vi and their preparation are known from the literature. These substances are described, for example, in U.S. Pat. No. 4,127,405, U.S. Pat. No. 4,305,884, European Patent A-13,480, European Patent A-44,807 and European Patent A-44,808.

The aminopyrazinones and aminotriazinones of the formula II used as starting materials are known in some cases from the literature. The novel compounds of the formula II have been developed and prepared specifically for the preparation of the active substances according to the invention. They therefore form part of the present invention. These compounds are those of the formula II, with the proviso that R³ is C₁ -C₃ -alkyl if (a) at the same time E is nitrogen, R¹ is methyl and R² is methyl or methylthio; or (b) at the same time R¹ is methyl, R² is hydrogen and E is the group ═CCL-- or ═CH--.

The carbamates of the formula V are obtained from the amino compounds of the formula II by reaction with carbonic acid derivatives of the formula VII

    (RO).sub.2 C═X                                         (VII)

in which R and X are as defined above.

The carbonic acid derivatives of the formula VII are known and some of them are commercially available.

The starting materials of the formula II can be prepared by various methods depending on the substitution sought.

Thus, the aminotriazinones of the sub-formula IIa ##STR15## in which R¹ and R₃ are as defined under formula I and R² is C₁ -C₃ -alkyl, C₁ -C₃ -halogenoalkyl, hydrogen or C₁ -C₃ -alkylthio, are obtained by reacting a compound of the formula VIII ##STR16## in which R¹ and R² are as defined under formula IIa, with an oxalic acid derivative of the formula IX ##STR17## in which R³ is as defined under formula II and R is alkyl or aryl.

Aminotriazinone synthesis of this type are described in Leibig's Ann. Chem. 1984, 283-295. The intermediate products VIII and IX are known or can be obtained by processes analogous to published processes. The aminotriazinones of the sub-formula IIa in which R¹ and R³ are as defined under formula I and R² is is C₁ -C₃ -alkoxy, C₂ -C₃ -halogenoalkoxy, halogen or --NR⁵ R⁶ are obtained by oxidizing aminotriazinones of the formula IIa in which R² is C₁ -C₃ -alkylthio with suitable oxidizing agents, such as H₂ O₃ or Cl₂, and subsequently reacting the products with nucleophiles of the formula X

    H--R                                                       (X)

in which R is C₁ -C₃ -alkoxy, C₂ -C₃ -halogenoalkoxy or --NR⁵ R⁶, in appropriate in the presence of a base.

The aminopyrazinones of the sub-formula IIB ##STR18## in which R¹, R², R³ and R⁴ are as defined under formula I, are prepared by reacting a 2-amino-pyrazinone of the formula XI ##STR19## in which R², R³ and R⁴ are as defined under formula I, with alkylating agents, for example alkyl halides, alkyl tosylates or dialkyl sulfates, in the presence of a base. Alkylations of this type are described, for example, in J. Chem. Soc. 1965, 6681. Starting substances of the formula XI are known or can be obtained by methods analogous to published methods.

Aminopyrazines of the formula IIb are also obtained by reacting pyrazinones of the formula XII ##STR20## in which R¹, R² and R⁴ are as defined under formula I and X is Cl, Br or OSO₂ CF₃, with an amine of the formula XIII

    H.sub.2 N--R.sup.3                                         (XIII)

in which R³ is hydrogen or C₁ -C₃ -alkyl. Syntheses of this type are described in J. Het. Chem. 20, 919-923 (1983).

Pyrazinones of the sub-formula XIIa ##STR21## in which R² is hydrogen or C₁ -C₄ -alkyl, R⁴ is --NR⁵ R⁶, C₁ -C₃ -alkylthio, C₁ -C₃ -alkoxy or C₂ -C₃ -halogenoalkoxy and R¹ and X are as defined in formula XII, are prepared by reacting pyrazinones of the formula XIV ##STR22## in which R¹, R² and R⁴ are as defined in formula XIIa, with (CF₃ SO₂)O, PCl₅, POCl₃, POBr₃, (COCl)₂ or (COBr)₂, if appropriate in the presence of a base, in inert solvents, such as, for example, dichloromethane, acetonitrile, chloroform or carbon tetrachloride.

Pyrazinones of the formula XIV or alkali metal salts thereof are obtained by acylating aminoalkylcyanides of the formula XV ##STR23## in which R¹ is C₁ -C₄ -alkyl and R² is hydrogen or C₁ -C₃ -alkyl, with oxalic acid chlorides of the formula XVI in which R is C₁ -C₃ -alkyl, and subsequently reacting the products with nucleophiles of the formula XVII,

    H--R.sup.4                                                 (XVII)

in which R⁴ is as defined in formula XIIa, if appropriate in the presence of a base.

The pyrazinones of the sub-formula XIIb ##STR24## in which R¹ is C₁ -C₄ -alkyl, R² is hydrogen or C₁ -C₃ -alkyl and X and R⁴ are chlorine or bromine, are obtained by reacting aminoalkyl cyanides of the formula XV with oxalyl chloride or bromide.

Syntheses of this type and pyrazinones of the formula XIIb are described in J. Het. Chem. 20, 919-923 (1983).

The pyrazinones of the sub-formula XIIc ##STR25## in which R¹, R² and R⁴ are as defined in formula I and X is chlorine or bromine, are obtained by reacting pyrazinones of the formula XVIII ##STR26## in which R², R⁴ and X are as defined under formula XIIc, with alkylating agents, for example alkyl halides, alkyl tosylates or dialkyl sulfates, in the presence of a base. The starting substances of the formula XVIII are known or can be obtained by methods analagous to published methods.

The active substances of the formula I are stable compounds. Their handling requires no precautionary measures.

When applied to relatively small amounts, the compounds of the formula I are distinguished by good selective growth-inhibiting and selective herbicidal properties, which makes them excellently suitable for use in crops of useful plants, in particular in cereals, rice, cotton, soybean and maize. In some cases, weeds which were previously to be controlled only with total herbicides are also damaged.

The mode of action of these active substances is unusual. Many of them are transloctable, i.e. they are taken up by the plant and transported to other points, where they then act. It is thus possible, for example, to damage perennial weeds down to the roots by surface treatment. In contrast to other herbicides and growth regulators, the novel compounds of the formula I already act when very low amounts are applied.

The compounds of the formula I also have potent plant growth-regulating, in particular plant growth-inhibiting, properties. The growth of both monocotyledons and dicotyledons is impaired.

Thus, for example, the growth of leguminosae frequently planted as cover crops in agriculture in topical regions can be selectively inhibited by the compounds of the formula I, so that although soil erosion between the crop plants is prevented, the cover crops cannot become competition for the crop.

For many crop plants, an inhibition of vegetative growth allows denser planting of the crop, so that an increased harvest, based on the soil surface, can be achieved.

Another mechanism of increasing yield with growth inhibitors is based on the fact that the nutrients benefit blossom and fruit formation to a greater degree, whilst vegetative growth is restricted.

When larger amounts of active substances of the formula I are applied, the development of all the plants tested is damaged to the extent that they die.

The invention also relates to herbicidal and plant growth-regulating compositions which contain a novel active substance of the formula I, and to processes for pre- and post-emergence weed control and for inhibition of the growth of monocotyledon and dicotyledon plants, in particular grasses, tropical cover crops and tobacco side shoots.

The compounds of the formula I are used in non-modified form or, preferably, as compositions together with the auxilaries customary in formulation technology, and are therefore processed in a known manner to emulsion concentrates, directly sprayable or dilutable solutions, diluted emulsions, wettable powders, soluble powders, dusts, granules or encapsulations in, for example, polymeric substances. The methods of use, such as spraying, misting, dusting, scattering or watering, like the nature of the agent, are chosen according to the intended aims and the given circumstances.

The formulations, i.e. the compositions, formulations or combinations containing the active substance of the formula I and if appropriate a solid or liquid additive are prepared in an known manner, for example by intimate mixing and/or grinding of the active substances with extenders, for example with solvents, solid carriers and if appropriate surface-active compounds (surfactants).

Possible solvents are: aromatic hydrocarbons, preferably C₈ to C₁₂ fractions, for example xylene mixtures or substituted naphthalenes, phthalic acid esters, such as dibutyl or dioctyl phthalate, aliphatic hydrocarbons, such as cyclohexane or paraffins, alcohols and glycols and ethers and esters thereof, such as ethanol, ethylene glycol or ethylene glycol monomethyl or monethyl ether, ketones, such as cyclohexanone, highly polar solvents, such as N-methyl-2-pyrrolidone, dimethylsulfoxide or dimethylformamide, and if appropriate epoxidized vegetable oils, such as epoxidized coconut oil or soybean oil; or water.

The solid carriers used, for example for dusts and dispersible powders, are as a rule natural rock powders, such as calcite, talc, kaolin, montmorillonite or attapulgite. Highly disperse silicic acid or highly disperse absorbent polymers can also be added to improve the physical properties. Possible granular adsorptive granule carriers are porous types, for example pumice, crushed brick, sepiolite or bentonite, and possible non-adsorptive carrier materials are, for example, calite or sand. A large number of pre-granulated materials of inorganic or organic nature, such as, in particular, dolomite or comminuted plant residues, can moreover be used.

Possible surface-active compounds are, depending on the nature of the active substance of the formula I to be formulated, nonionic, cationic and/or anionic surfactants with good emulsifying, dispersing and wetting properties. Surfactants are also to be understood as meaning surfactant mixtures.

Suitable anionic surfactants can be either so-called water-soluble soaps or water-soluble synthetic surface-active compounds.

Soaps which may be mentioned are the alkali metal, alkaline earth metal or substituted or unsubstituted ammonium salts of higher fatty acids (C₁₀ -C₂₂), for example the Na or K salts of oleic or stearic acid, or of naturally occurring fatty acid mixtures which can be obtained, for example, from coconut oil or tallow oil. Fatty acid methyl-taurine salts may furthermore also be mentioned.

However, so-called synthetic surfactants, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates, are more frequently used.

The fatty sulfates or sulfonates are as a rule in the form of alkali metal, alkaline earth metal or substituted or unsubstituted ammonium salts and have an alkyl radical having 8 to 22 C atoms, alkyl also including the alkyl part of acyl radicals, for example the Na or Ca salt of the ligninsulfonic acid, of dodecylsulfuric acid ester or of a fatty alcohol sulfate mixture prepared from naturally occurring fatty acids. The salts of sulfuric acid esters and sulfonic acids of fatty alcohol-ethylene oxide adducts are also included here. The sulfonated benzimidazole derivatives preferably contain 2-sulfonic acid groups and a fatty acid radical having 8 to 22 C atoms. Alkylarylsulfonates are, for example, the Na, Ca or triethanolamine salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid-formaldehyde condensation product.

Corresponding phosphates, for example the salts of the phosphoric acid ester of a p-nonylphenol-(4-14)-ethylene oxide adduct or phospholipids, are furthermore also suitable.

Possible nonionic surfactants are in particular polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can contain 3 to 10 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols.

Other suitable nonionic surfactants are the water-soluble adducts, containing 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups, of polyethylene oxide on polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol having 1 to 10 carbon atoms in the alkyl chain, the compounds mentioned usually containing 1 to 5 ethylene glycol units per propylene glycol unit.

Examples which may be mentioned by nonionic surfactants are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene-polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol.

Fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate, are furthermore also possible.

The cationic surfactants are in particular quaternary ammonium salts which contain at least one alkyl radical with 8 to 22 C atoms as the N substituent and lower free or halogenated alkyl, benzyl or lower hydroxyalkyl radicals are further substituents. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, for example stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)-ethylammonium bromide.

Surfactants which are customary in formulation technology are described, inter alia, in the following publications: "McCutcheon's Detergents and Emulsifiers Annual" MC Publishing Corp., Ridgewood, N.J., 1981; H. Stache, "Tensid-Taschenbuch (Surfactant handbook)", 2nd edition, C. Hanser Verlag, Munich, Vienna, 1981; and M, and J. Ash. "Encyclopedia of Surfactants", volume I-III, Chemical Publishing Co., New York, 1980-1981.

The agrochemical formulations as a rule contain 0.1 to 95%, in particular 0.1 to 80%, of active substance of the formula I, 1 to 99.9% of a solid or liquid additive and 0 to 25%, in particular 0.1 to 25%, of a surfactant.

Preferred formulations have, in particular, the following compositions: (%=percent by weight).

Whilst concentrated compositions are preferred rather as commercial groups, the end user as a rule uses dilute compositions. The use forms can be diluted down to 0.001% of active substance. The amounts applied are as a rule 0.01 to 10 kg of active substance/ha, preferably 0.025 to 5 kg of active substance/ha.

The compositions can also contain further additives, such as stabilizers, foam suppressants, viscosity regulators, binders, tackifiers and fertilizers or other active substances, in order to achieve special effects.

BIOLOGICAL EXAMPLES EXAMPLE B1 Herbicidal action before emergence of the plants

Plastic pots are filled with expanded vermiculite (density: 0.135 g/cm³, water absorption capacity: 0.565 1/l). After the non-adsorptive vermiculite has been saturated with an aqueous emulsion of the active substance in deionized water, which contains the active substances in a concentration of 70.8 ppm, seeds of the following plants are sown on the surface: Nsturtium officinalis, Agrostis tenuis, Stellaria media and Digitaria sanguinalis. The experimental containers are then kept in a climatically controlled chamber at 20° C. under an illumination of about 20 klux and a relative atmospheric humidity of 70%. During a germination phase of 4 to 5 days, the pots are covered with material which is transparent to light in order to increase the local atmospheric humidity and are watered with deionized water. After the 5th day, 0.5% of a commercially available liquid fertilizer (®Greenzit, from Ciba-Geigy) is added to the water used for watering. 12 days after sowing, the experiment is evaluated and the action on the experimental plants is evaluated according to the following scale:

1: plants have not germinated or have completely died

2-3: very potent action

4-6: moderate action

7-8: weak action

9: no action (as untreated control).

EXAMPLE B2 Inhibition of growth of tropical leguminosae cover crops

The experimental plants (Centrosema plumieri and Centrosema pubescens) are grown to the fully developed stage and cut back to a height of 60 cm. After 7 days, they are sprayed with the active substance as an aqueous emulsion. The experimental plants are kept at 70% relative atmospheric humidity under 600 lux of artificial light for 14 hours per day at temperatures of 27° during the day and 21° C. during the night. 4 weeks after the application, the experiment is evaluated. The new additional growth is estimated and weighed in comparison with the control and the phytotoxicity is evaluated. In this experiment, the plants treated with the active substances of the formula I show a clear reduction in new additional growth (less than 20% of the new additional growth of untreated crop plants), without the experimental plants thereby being damaged.

EXAMPLE B3 Growth regulation in soyabean

Soybeans of the "Hark" variety are sown in plastic containers with a soil-peat-sand mixture in a ratio of 6:3:1 and the containers are placed in a climatically controlled chamber. By optimum choice of temperature, illumination, addition of fertilizer and watering, the plants develop to the 5-6 trefoil leafe stage after about 5 weeks. At this point in time, the plants are sprayed with an aqueous liquor of an active substance of the formula I and are wetted thoroughly. The active substance concentration is up to 100 g of active substance/ha. Evaluation is carried out about 5 weeks after application of the active substance. In comparison with untreated control plants, the active substances of the formula I according to the invention cause a notable increase in the number and weight of pods on the main shoot.

EXAMPLE B4 Inhibition of growth in cereals

The cereal varieties Hordeum vulgare (spring barley) and Secale (spring rye) are sown in plastic pots with sterilized soil in a greenhouse and are watered as required. About 21 days after sowing, the shoots are sprayed with an aqueous spray liquor of an active substance of the formula I. The amount of active substance is up to 100 g of active substance per hectare. The growth of the cereal is evaluated 21 days after the application. The treated plants show a reduction in new additional growth in comparison with the untreated controls (60-90% of the control), and in some cases an increase in stem diameter.

EXAMPLE B5 Inhibition of growth in grasses

The grasses Lolium perenne, Poa pratensis, Festuca ovina, Dactylis glomerate and Cynodon dactylon are sown in plastic dishes with a soil-peat-sand mixture (6:3:1) in a greenhouse and are watered as required. The emerged grasses are cut back weekly to a height of 4 cm and about 50 days after sowing and one day after the last cut are sprayed with an aqueous spray liquor of an active substance of the formula I. The amount of active substance, when converted, is up to 100 g of active substance per hectare. 21 days after the administration, the growth of the grasses is evaluated.

The compounds of the formula I effect a reduction in new additional growth of about 10-30% in comparison with the untreated control. 

What is claimed is:
 1. A compound of the formula II ##STR41## in which E is nitrogen, R¹ is C₁ -C₄ -alkyl, R² is hydrogen, C₁ -C₃ -alkyl, C₁ -C₃ -halogenoalkyl, C₁ -C₃ -alkoxy, C₁ -C₃ -halogenoalkoxy, C₁ -C₃ -alkylthio, C₁ -C₃ -alkylsulfinyl, C₁ -C₂ -alkoxyethoxy, C₁ -C₃ -alkylsulfonyl, halogen or --NR⁵ R⁶, R³ is hydrogen or C₁ -C₃ -alkyl, and R⁵ and R⁶ independently of one another are hydrogen or C₁ -C₃ -alkyl, with the proviso that R³ is C₁ -C₃ -alkyl if R¹ is methyl and R² is methyl or methylthio.
 2. 6-Amino-3-methoxy-4-methyl-1,2,4-triazin-5-one according to claim
